What Controls The F2 Machine Power Toggle?

Greetings All,

I have my Smithy CNC 1240 running to the point where I am actually making parts. However, it does not run perfectly. There are several "bugs" I would like to correct as I make machining progress.

I tried StepConf to create a brand new profile. I was able to create it and when I open Axis, the F2 toggle button is inactive. If I use the less than ideal existing config the F2 toggle works fine. So, I suspect it is controlled by the software, not a hardware issue.

I will attach my HAL and INI files for those that fully understand them and possibly point me to the line that controls the F2 toggle.

When I refer to the F2 toggle, I mean both pressing "F2" or mouse clicking.

Cheers,

Dave

Might be a dumb answer, but worth a try.
I have to hit F1 first, then F2 when I start out.

Greetings Big John,

I had some time to revisit this issue.

Your answer explained why the machine will not power on.

What do I do/change in the StepConfig application to make things work?

With kind regards,

David

stepconf often produces a linkage to estop with the charge_pump that does not work with some setups and leaves them disabled.

Greetings JT,

Thanks, in advance, for your offer of help.

As requested, please find attached "my-mill.stepconf".

When I initiate the AXIS program, the AXIS window appears as normal; but, I cannot turn on the machine via F1 or F2. Either with keyboard presses or mouse clicks.

I also added the PDF manual of my BreakOut Board and a screen dump of the Parallel Port Setup page. I was stumped what to pick for Pin 11. The manual says "pin 11 > inhibit switch status to PC" however, I could not find a suitable pick from the drop down menu. Additionally, I have no clue what is being "inhibited".

As I write this, the machine is warming up for some cutting using the "Smithy configured files". Sadly, Smithy no longer offers support for this machine and I really need to be able to configure it on my own in case of failure.

Cheers,

Dave

An inhibit signal into the control from the machine, could be several things, such as a door interlock signal, a drive fault, or what ever the machine tool builder could imagine for it.

My guess why you were not able to power on with your config is that there is something wrong with the e-stop signal you have programmed for pin 10. That signal has to be present for Linuxcnc to come out of e-stop and power up (F1 & F2). If you have it connected you might only need to invert the signal.
